I am no expert, coz i dont play this stuff, but i think that either the Brahms or Busoni Cadenzas are used generally.Thal
Brahms and Busoni?!? That's about as far from Mozart's style as you can get! Generally when playing Mozart concerti as difficult as that one, you're expected to be able to improvise your own cadenza. I don't know what you do if not, though.
If not improvisation, I know many performers on occasion write their own beforehand. Brahms and Busoni wrote fairly good cadenzas; I don't think the point is necessarily to sound like Mozart in terms of style, but to capture the theme and the heart of the piece. It really is all up to the performer.
if you are intent on playing the K 467 first, you can also listen to murray perahia's. they are very good. someone else mentioned cassedesus - who was also recommended. the problem is, finding these cadenzas or getting them transcribed off cd. i don't know who does this. i was looking for someone to do that very thing for my 'piano concerto' class. badura-skoda's was cut and pasted by ashkenazy, i think. it sounds ok. but i like murray perahia's the best. short and sweet. mozart's were fairly short, usually. beethoven gets wild and modulates farther than he should - and lengthens the cadenzas with more of a 'development' than mozart did.
barenreiter urtext has all the mozart cadenzas extant (i think) - but you can also imagine from reading the forward that some have probably gone missing. the idea that he always extemporaneously played cadenzas isn't totally true. he often had folios of his candenzas and kept them closely guarded.
and, of course, you have all the extant cadenzas written for his own concerti. that would be the safest way to go. to play some of the ones that DO have cadenzas and get used to how they sound and what is 'appropriate.' mozart's 'a musical joke' jested about how music can be 'second rate, superficial, stubbornly and enduringly devoid of any significant idea.' he violates elementary laws of composition by creating consecutive fifths and octaves, doubling parts without account for texture, creating overly intrusive accompaniment in sections, and music that goes nowhere and cannot come to the cadence appropriately. when the cadenza arrives for the violin, it is overtly an example of how a cadenza should not be written. what i like about murray perahia's is that they are 'sparkling and effervescent' rather than long and tedious.
Thanks for your ideas and great information. However I wonder if there are the cadenza by Murray Perahia on score ?If so, where can i find this one?Thanks!
